 a fourth sub-barrier extending lengthwise in the first direction and spaced apart from the first sub-barrier in the second direction, and 
 wherein the seating area is interposed between the first sub-barrier and the fourth sub-barrier. 
 
     
     
       7. The display panel inspection jig of  claim 1 ,
 wherein the first barrier is integrally formed with the stage. 
 
     
     
       8. The display panel inspection jig of  claim 1 , further comprising:
 a second barrier disposed on a third portion of the uneven upper surface at the seating area of the stage, 
 wherein, when the display panel is viewed in a plan view, the second barrier is spaced apart from the first supporter and the first barrier. 
 
     
     
       9. The display panel inspection jig of  claim 8 ,
 wherein an upper surface of the first supporter is disposed at a first height from the lower surface of the stage, 
 wherein an upper surface of the second barrier is disposed at a second height from the lower surface of the stage, 
 wherein the second height is equal to or smaller than the first height, and 
 wherein the lower surface of the stage is flat. 
 
     
     
       10. The display panel inspection jig of  claim 9 ,
 wherein a difference between the first height and the second height is equal to or smaller than about 0.2 mm. 
 
     
     
       11. The display panel inspection jig of  claim 8 ,
 wherein the second barrier comprises: 
 a first auxiliary barrier disposed adjacent to the opening of the stage; 
 a second auxiliary barrier connected to a first end of the first auxiliary barrier and extending away from the opening of the stage; and 
 a third auxiliary barrier connected to a second end of the first auxiliary barrier and extending away from the opening of the stage, and 
 wherein the second auxiliary barrier and the third auxiliary barrier are spaced apart from each other in a direction in which the first auxiliary barrier extends. 
 
     
     
       12. The display panel inspection jig of  claim 11 ,
 wherein the second barrier further comprises: 
 a fourth auxiliary barrier spaced apart from the first auxiliary barrier in the direction in which each of the second auxiliary barrier and the third auxiliary barrier extends away from the opening of the stage, and 
 wherein the second auxiliary barrier is connected to a first end of the fourth auxiliary barrier, and the third auxiliary barrier is connected to a second end of the fourth auxiliary barrier. 
 
     
     
       13. The display panel inspection jig of  claim 8 ,
 wherein, when the display panel inspection jig is viewed in a plan view, the second barrier is spaced apart from the opening and forms a closed line.
